[Pixel C Q&A, Help & Troubleshooting] brando56894:
We we're all beginners once but laziness is not an acceptable excuse. If you would have even glanced an inch down from General on the Pixel C section of the XDA website you would have clearly seen two out of the only three threads in Android Development talk about root, if you would have looked at the very first thread (Xceed kernel) you would have clearly seen that it IS rootable and how to go about doing it. Also if you even glanced at Original Android Development and took a look at MSkip's thread about his toolkit it is a simple utility that allows you to unlock and root (not sure if he added this in yet) your device with the press of a button. Hell you could have even googled "pixel c root" and been shown various pages that would say that it is rootable. How much more obvious do you want it to be?

Your last sentence is ridiculous, that's like saying "Can I transplant a person's heart without knowing a single thing about medicine?" The answer is yes, but you'll most likely screw something up then come crying to us to fix it for you when your $500 tablet is dead. You seem to know absolutely nothing about Android, yet you know what rooting is (do you actually know what it means, or is it just a term you learned?), if you want to mess around with Android and get your feet wet with rooting and modding, get a Nexus device, they're a lot harder (neigh impossible) to brick. There is very little development for ANY tablet, and this is an especially odd one since it was originally meant to be a ChromeOS device, but at the last second they decided to throw Android on it instead so the bootloader is completely different than your standard Android device, which means the rooting process is different than any other Android device. Rooting and modding Android devices is not a simple "one and done" thing like jailbreaking an iPhone is (I did it years ago to an ex's iPhone 4 and actually found it far more complicated than unlocking a Nexus device, other devices are a different story). You actually have to know what you're doing and how to fix it in the event that something doesn't work correctly. I have rooted friends phones before when they asked me to and had no idea what to do when I gave it back to them so every time something went goofy they would come running to me to fix it for them, then blame me when something doesn't work the way they expected it to.

Read up on how to unlock a Nexus device (It literally takes about 30 seconds and three words you have to type), then how to flash a recovery image (once again, only 4 words and another 30 seconds). Sorry for sounding like an asshole but a lot of us here don't tolerate helpless users and if you keep asking questions like this where there are obvious answers you continually get this type of response. It would be more understandable if this forum section was overloaded with tons of threads and the information buried deep within a 50 page thread in one of the sub sections (I've been guilty of that and I've been here for years), but once again, there are literally like 3 threads in the development sections and the info is in the first page of the first thread.

edit: I just looked at the link you posted and if you can't follow a simple step by step instruction manual which provides you with literally everything you need, don't even attempt it because you obviously have no clue what you're doing and I'm going to assume you're not a techy person because that's actually pretty simple. You should have been here a month ago when we had partially broken root access, you would have been scared to death! Try rooting the old HTC Rezound for Verizon which required a hardware mod, or try to root a Samsung Galaxy device without tripping Knox, or getting rid of it completely, then restoring it to a factory state and make it look like Knox was never removed. If you can't press a few buttons on your device to enable dev mode, then type a few commands to unlock the bootloader you're going to be completely lost later on when it comes to flashing partitions and flashing and learning about kernels. Get the Pixel C, it's a great device, root doesn't add that much functionality for now, but I wouldn't suggest even attempting to root it because you clearly lack the desire to learn anything about the rooting process and just want to do it so you can say "I rooted my Pixel C! Now what do I do with it?" I've seen tons of these types of posts, which makes the user look dumb because they don't even know why they did it in the first place, they just knew it was something "cool" to do.
